The equipment can reach the set light intensity within 100 milliseconds and output stably, supporting immediate use, significantly improving the utilization efficiency and energy efficiency of laboratory equipment.

4. Independent LED flexible control The light source of the large-area LED solar light simulator can automatically provide optimized calibrated output to meet the requirements of the solar spectrum, and also supports independent control of each LED output and changing the total irradiance output. The independent control of each LED allows users to adjust the output according to the specific requirements of the test. The entire spectrum can be adjusted on the front panel or remotely controlled via USB port. All adjusted spectral parameters can be saved as custom presets, greatly enhancing the flexibility and repeatability of the test. Application value of large-area LED solar light simulator luminbox 1.
